5. Precautions on Using R8C UART Debugger

5.1. When changing the communication speed and restarting the R8C

UART debugger after the R8C UART debugger ends.

The target MCU holds the baud rate value after the R8C UART debugger ends. Therefore,

when changing the communication speed and restarting the R8C UART debugger, a

communication error occurs. (The R8C UART debugger can be started when using the

previous communication speed). When changing the communication speed, turn off the

target power and turn on the power again.

5.2. ID code of user program

Set the ID code of the user program to all FFh when using the R8C UART debugger.

0FFF7h – 0FFF4h ID6 Address Break

0FFFBh – 0FFF8h ID7 Reserved

0FFFFh – 0FFFCh (NOTES 1) Reset

NOTES

1. Refer to the hardware manual for the value set in 0FFFFh.
